What are the characteristics of hard-sealed worm gear butterfly valve?
The hard-sealed turbine butterfly valve seal is composed of a stack of soft and hard metal sheets. It is formed by high-precision machining and fits on the disc plate to match the valve seat. It has the dual advantages of metal sealing and elastic sealing, regardless of low temperature and high temperature conditions. , all have excellent sealing properties.
The hard-sealed worm-wheel butterfly valve adopts a three-dimensional eccentric structure and the disc plate has almost no friction, and has a tighter sealing function. Its unique structure, flexible operation, labor-saving, convenient, high pressure and low pressure from the media, reliable sealing performance, long service life.
The
The hard-sealed turbine butterfly valve is equipped with a sealing adjustment device. If the sealing performance is degraded after long-term use, the adjustable sealing ring of the disc plate can be restored to the valve seat to restore the original sealing performance and greatly increase the service life.
